List of common errors leading to "failure" in Batch Searches
One or several of your queries contains syntax errors.
It means that you wrote one or more of your queries the wrong way with some characters that are reserved as operators: read the list of syntax errors by clicking here.
You need to correct the error(s) in your CSV and re-launch your new batch search with a CSV that does not contain errors. Click here to learn how to launch a batch search.
Datashare stops at the first syntax error. It reports only the first error. You might need to check all your queries as some errors can remain after correcting the first one.
Example of a syntax error message:
SearchException: query='AND ada' message='org.icij.datashare.batch.SearchException: org.elasticsearch.client.ResponseException: method [POST], host [http://elasticsearch:9200], URI [/local-datashare/doc/_search?typed_keys=true&ignore_unavailable=false&expand_wildcards=open&allow_no_indices=true&scroll=60000ms&search_type=query_then_fetch&batched_reduce_size=512], status line [HTTP/1.1 400 Bad Request] {"error":{"root_cause":[{"type":"query_shard_exception","reason":"Failed to parse query [AND ada]","index_uuid":"pDkhK33BQGOEL59-4cw0KA","index":"local-datashare"}],"type":"search_phase_execution_exception","reason":"all shards failed","phase":"query","grouped":true,"failed_shards":[{"shard":0,"index":"local-datashare","node":"_jPzt7JtSm6IgUqrtxNsjw","reason":{"type":"query_shard_exception","reason":"Failed to parse query [AND ada]","index_uuid":"pDkhK33BQGOEL59-4cw0KA","index":"local-datashare","caused_by":{"type":"parse_exception","reason":"Cannot parse 'AND ada': Encountered " <AND> "AND "" at line 1, column 0.\nWas expecting one of:\n <NOT> ...\n "+" ...\n "-" ...\n <BAREOPER> ...\n "(" ...\n "*" ...\n <QUOTED> ...\n <TERM> ...\n <PREFIXTERM> ...\n <WILDTERM> ...\n <REGEXPTERM> ...\n "[" ...\n "{" ...\n <NUMBER> ...\n <TERM> ...\n ","caused_by":{"type":"parse_exception","reason":"Encountered " <AND> "AND "" at line 1, column 0.\nWas expecting one of:\n <NOT> ...\n "+" ...\n "-" ...\n <BAREOPER> ...\n "(" ...\n "*" ...\n <QUOTED> ...\n <TERM> ...\n <PREFIXTERM> ...\n <WILDTERM> ...\n <REGEXPTERM> ...\n "[" ...\n "{" ...\n <NUMBER> ...\n <TERM> ...\n "}}}}]},"status":400}'
If you have a message which contain 'elasticsearch: Name does not resolve', it means that Datashare can't make Elastic Search, its search engine, work.
Example of a message regarding a problem with ElasticSearch:
SearchException: query='lovelace' message='org.icij.datashare.batch.SearchException: java.io.IOException: elasticsearch: Name does not resolve'
